One of the major contribution of Robert Boyle is "Boyle's Law" which states that the pressure exerted by a gas state is inversely proportional to its volume at a constant temperature which in fact should be in a closed system; which means that if pressure increases the volume will decrease as well.
Some basic examples would be:
1. A balloon that has too much air will pop.
2. Pumping a tire can have its limit.
3. When we open soda cans.
